Prove: 

Answer 1

prove what ?? this  ?? :D

Answer 2

really low quality picture .-. but thats what I need..

Answer 3

angle 1 and angle too add up to a straight line right

Answer 4

two*

Answer 5

IF
the sum of angle 1 and angle 2 adds up to a straight angle of 180, they are suppl angles

AND
IF

angle 1 = angle 2

THen
angle 1 and angle 2 must be 90 degrees , right angles

Answer 6

because you can show if angle 1 = angle 2
and
1 + 2 = 180

Angle 1 + angle 1 = 180
2*Angle 1 = 180

Angle 1 = 90, right
